Dean Jeffries' Mantaray is a car that's been in our consciousness as long as we can remember, although we never knew some of the facts behind it until just now. Built from a couple of Maserati Grand Prix chassis of 1950s vintage, the Mantaray sports a healthy small-block Ford with Weber carbs, given to Jeffries by none other than Carroll Shelby himself. We'd always assumed, that like Ed Roth's Beatnik Bandit, the Mantaray's body was fiberglass. Not so. Jeffries hand-formed the whole thing out of 86 pieces of aluminum sheet. After this, he went on to build the most famous GM A-body phaeton ever The Monkeemobile.
